Hi, I am trying to add a stack reference, but keep encountering this error: `registered twice (read and read)`. Does anyone know how to fix this?

Example code:
```            var stackNames = new List&lt;string&gt; { "stack1", "stack2" };
            
            var backendPools = stackNames.Select(stack =&gt;
            {
                var stackRef = new StackReference($"{stack}ref", new StackReferenceArgs { Name = $"company/project/{stack}" });

                var output1 = stackRef.RequireOutput("output1").Apply(_ =&gt; _.ToString());
                var output2 = stackRef.RequireOutput("output2").Apply(_ =&gt; _.ToString());

                return GetBackendPoolArgs(..);
            });```

ah, got my `name` param mixed up with the stack name. All good now!

actually, that wasn't it after all. Still need help on this please.

in my code, the names are different. I've updated the example - do you know what would throw that error?

I’d still guess two stack references with the same name somehow…
